How to Fix Minecraft LAN Not Working: A Step-by-Step Guide

Minecraft is a favorite for millions of gamers due to its engaging gameplay and collaborative multiplayer features. One of these features, Local Area Network (LAN) mode, allows players on the same network to join a shared world. However, LAN issues can sometimes prevent players from connecting, leading to frustration. This guide provides a comprehensive, step-by-step solution to fix Minecraft LAN not working.

Common Causes of Minecraft LAN Issues

Several reasons can cause LAN connections in Minecraft to fail:

• • Firewall Restrictions: Your device’s firewall might block Minecraft’s LAN connection.
  • Version Mismatch: Players may be using different versions of Minecraft.
  • IP or Network Configuration Issues: Devices might not be on the same network or use incorrect IP settings.
  • Outdated Software: An outdated version of Minecraft or Java can disrupt LAN connectivity.
  • Incorrect Game Settings: The “Open to LAN” setting might not be properly enabled.

Understanding these common issues is the first step toward resolving LAN connectivity problems.

Step-by-Step Solutions to Fix Minecraft LAN Issues

Step 1: Ensure All Devices Are on the Same Network

• Confirm that all devices are connected to the same Wi-Fi or Ethernet network.
• Avoid using guest networks or networks with isolation features (e.g., AP isolation).

Device	IP Address	Status
Computer 1	192.168.0.101	Same Network
Computer 2	192.168.0.102	Same Network
Router Gateway	192.168.0.1	Correct Subnet

To check your IP address on Windows:

1. Open Command Prompt.
2. Type ipconfig and press Enter.
3. Look for the IPv4 address under your network adapter.

Step 2: Open the World to LAN

1. Launch Minecraft and open your world.
2. Press Escape to access the pause menu.
3. Select Open to LAN.
4. Adjust settings like Game Mode and toggle Allow Cheats as needed.
5. Note the displayed port number (e.g., 12345).

Step 3: Verify Firewall Settings

Sometimes, your firewall can block Minecraft’s LAN traffic. To fix this:

1. Open Control Panel and navigate to System and Security > Windows Defender Firewall.
2. Click on Allow an app through the firewall.
3. Find Minecraft in the list and ensure that both Private and Public boxes are checked.

For Mac users:

• Go to System Preferences > Security & Privacy > Firewall Options and add Minecraft to the exceptions list.

Step 4: Sync Minecraft Versions

LAN connections fail if players are using different versions of Minecraft. Ensure all devices are running the same version:

1. Open the Minecraft Launcher.
2. Go to Installations.
3. Create a new installation or edit the current one to match the version of the host.

Player	Version	Status
Player 1	1.20.1	Compatible
Player 2	1.20.1	Compatible

Step 5: Update Java and Minecraft

An outdated Java installation can cause LAN issues, especially for the Java Edition of Minecraft. Update Java by downloading the latest version from the official Oracle website.

Also, ensure Minecraft is up-to-date:

1. Open the Minecraft Launcher.
2. Click on Latest Release.
3. Install updates if available.

Step 6: Use Direct Connect

If the LAN game isn’t visible, try connecting directly using the host’s IP address and port number:

1. Obtain the host’s IP address:
   • On Windows, use ipconfig in Command Prompt to find the IPv4 address.
   • On Mac, use ifconfig in Terminal.
2. Note the port displayed during the Open to LAN process.
3. On the client device, select Direct Connect and enter the IP and port (e.g., 192.168.0.101:12345).

Step 7: Temporarily Disable Antivirus

Antivirus programs may block Minecraft’s network access. Temporarily disable your antivirus software and check if the issue resolves. If it works, whitelist Minecraft within the antivirus settings.

Advanced Troubleshooting

a) Disable Antivirus Temporarily

Sometimes, third-party antivirus software can block LAN connections. Temporarily disable your antivirus to see if it resolves the issue.

b) Manually Connect via Direct IP

If the automatic LAN discovery fails:

1. Obtain the host’s IP address:
   • Use ipconfig on Windows or ifconfig on macOS.
   • Note the IPv4 address (e.g., 192.168.1.2).
2. On the guest device, click Direct Connect in Minecraft.
3. Enter the host’s IP followed by the port number (e.g., 192.168.1.2:12345).

FAQs on Minecraft LAN

1. Can I play LAN if one device is wired and the other is wireless?
Yes, as long as both devices are on the same network.

2. Why isn’t the LAN game showing up in my multiplayer menu?
The host’s firewall or incorrect IP configuration might be blocking the connection. Use Direct Connect as a workaround.

3. Are there mods that improve LAN connectivity?
Yes, mods like Essentials Mod or server software like PaperMC can improve LAN gameplay.

Final Thoughts

Fixing Minecraft LAN issues requires a systematic approach, from ensuring network compatibility to updating software. By following these steps, you can resolve most LAN-related problems and enjoy seamless multiplayer gameplay with friends. Regularly updating your game, Java, and network settings can prevent future issues.
